Keeping up with the correct botanical names for the full roster of Pygmy Drosera has been a complex task over the past 20 years, consequently many plants in cultivation have been incorrectly labeled and continue to be so today. The release of Magnum Opus by Lowrie in 2014, went a long way to clearing up this confusion. With exhaustive field work, literature reviews and herbarium studies, Lowrie cleared up previous errors, matched the correct type material to plants that had been elusive in the field and also ensuring that the first published name of a species stands as the correct name. The roster of names published in Magnum Opus is now accepted as the benchmark work for the correct naming of Pygmy Drosera, and this treatment was followed in the 3 volume Drosera of the World.
More recently two species Lowrie described, Drosera coalara and Drosera micra, have been reduced to synonymy, leaving us with the roster of species treated in the Pygmy Drosera resource. The result of this work has seen a lot of plant material in cultivation being mislabled, for example the plant that was widely known in cultivation as Drosera dichrosepala was in fact not the true Drosera dichrosepala and was given the name Drosera verrucata when the true Drosera dichrosepala was rediscovered. The tables below and using the Pygmy Drosera resource should help Pygmy Drosera growers correctly label their collections.
Recent changes of note to growers.
